title: Somatosensory evoked potentials in children with migraine with aura and without aura.
abstract: BACKGROUND
  The Interictal abnormalities of cerebral information processing in migraine were found by studying different modality-specific evoked and event related potentials, mostly visual and auditory. In this study we focused on short-latency somatosensory evoked potentials (SEP) in children and adolescents suffering from migraine with and without aura.
  
  
  METHODS
  The study group consisted 111 of children and adolescents at the age of 7-18 years: 27 of them suffered from migraine with aura, 36 of them suffered from migraine without aura, 48 subjects have episodic tension-type headache. SEPs was performed interictally at least two days after the last headache attack.
  
  
  RESULTS
  There were no significant differences in the latency averages of SEP components between all migraneurs and tension-type headache subjects. However, N9 and N13 latency averages were significantly shorter in migraine without aura group compared with migraine with aura and tensiom type headaches. We did not find any significant correlations for either headache type between evoked potentials parametrs and illness duration, unilateral localisation of pain, migraine in family and aura.
  
  
  CONCLUSIONS
  In concert with similar studies in adult migraineurs, our findings showed no disturbances of somatosensory information processing in children with migraine with aura and without aura. The diagnosis of migraine in children actually remains predominantly based on medical history. However, electrophysiological techniques allow the study of some of the structures in vivo and enlarge our knowledge on controversial aspects of migraine pathophysiology.
